Use field exceptions to modify the normal interpretation and verification of fields on documents (which are controlled by document profiles and their field profiles). You can apply these modifications to one or more receivers (including entire corporate groups).
Create one or more field specifications.
You can create extra format specifications for any given field. This is helpful when documents from the same sender issued to different cost centers and/or service centers ( receivers) within your organization contain different formats for certain fields.
If a particular field always contains the same prefix, specifying the prefix in a field specification improves interpretation of that field.
If a field that is captured by one receiver is not needed by another receiver, you can create a field specification to ignore such fields.
Create field rules that specify when the field specifications apply.
